9 Ways to Manipulate
People with Design
Designing products is
designing experiences
Best products create
lasting connections
That’s probably
Facebook
You can design for connections
We are vain, cheap
and easily amused
1. Familiarity Bias
Best new things
use familiar patterns
Familiar moments create trust
Make it easy to get to know you
Design patterns make new
interfaces feel familiar
Unfamiliar patterns
create confusion
(at least, at first)
2. Relative Value
Comparing is easier
than appraising
Options make us feel in control
Too many options
create choice paralysis
Things that are limited
have more value
3. Bandwagon
We are easily swayed by
behaviors and opinions of others
Strength in numbers
Bandwagon can also
work against you
4. Authority
Authority can trump
our own beliefs
Experiment:
“Teacher” instructed to administer
electric shock for “Student’s” wrong answer
65% obeyed, even though
they wanted to stop
No, let’s not electrocute
anyone, please.
Instead...
Be strategic with placement
5. Faith in Aesthetics
We first judge the site
by its appearance, then
consider its content
Study:
Would you trust a health site?
83% negative comments
stemmed from aesthetics
Attractive things
appear more valuable
Aesthetics affect usability
Study:
Complete tasks on this phone
Faster task completion
on visually appealing
devices
6. Achievement
Competition is great,
but we like to win
We like challenges that are
sort of challenging
We appreciate rewards more
when we don’t expect them
It’s science!
Unpredictable rewards cause
greater dopamine levels
We like showing off
7. Zeigarnik Effect
When we become engaged
in a story, we have to see
how it ends
We generally like to finish
what we start
Experiment:
Complete a jigsaw puzzle in time
90% continued after
time was called
The key is getting us
to start something
Varying the length of steps
keeps us motivated
Sometimes a guilt trip works best
8. Self-expression
We are unique, special
snowflakes
We perceive things we own
(or create) as more valuable
Find ways to make the
experience feel personalized
Keep personalization
options small
9. Surprise & Delight
We remember key moments
in our experiences
Only highs and lows
Create the “highs”
Validate the “lows”
So many nobs, girl
Familiarity Bias
Show me something
I already understand
Relative Value
Give me a comparison
Bandwagon
Tell me I’m missing out
Authority
Prove that it’s worth
my while
Faith in Aesthetics
Make it attractive
Achievement
Make it a fun game
Zeigarnik Effect
Help me get closure
Self-expression
Let me feel unique
Surprise & Delight
Entertain me
